invalid escape sequences in bitmask-root

The use of combination of python3.12 and bitmask-root leads to some warnings:

pea@peabox:bitmask-vpn-misc /usr/bin//bitmask-root
/home/pea/projects/leap/bitmask-vpn-misc/./bitmask-root:177: SyntaxWarning: invalid escape sequence '\d'
  "NUMBER": lambda s: re.match("^\d+$", s),
/home/pea/projects/leap/bitmask-vpn-misc/./bitmask-root:180: SyntaxWarning: invalid escape sequence '\:'
  "CIPHER": lambda s: re.match("^[A-Z0-9-\:]+$", s),
/home/pea/projects/leap/bitmask-vpn-misc/./bitmask-root:182: SyntaxWarning: invalid escape sequence '\.'

  if QUBES_PROXY and QUBES_VER >= 3 and run("grep", "installed\ by\ " +
bitmask-root: ERROR: No such command. Try bitmask-root help

These are shown in the bitmask log:

What's new in python

A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence, use raw strings for regular expression: re.compile(r"\d+.\d+")). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning. (Contributed by Victor Stinner in gh-98401.)
